During World War I, Iowa State trained soldiers for the Military. Military draftees were trained as auto mechanics, blacksmiths or machinists. They were housed under the bleachers on State Field. Instruction was mainly in practical assembly, repair, and operation processes, and entirely separate from collegiate work, This detachment of trainees was known as the Student Army Training Corps (S.A.T.C.). College students between the ages of 18 and 21 years were also able to volunteer for induction into active service. These students combined collegiate campus and army camp, by participating in scholastic study and military drill. A distinct separation of the collegiate and vocational sections was maintained in organization and instruction. The collegiate companies were lodged in fraternity houses and state gym was utilized as a mess hall.
